How awesome is this? A live webcam in Alaska that shows the aurorae! Since it's live, it will only show the aurorae 1) when they are active, and 2) when it's nighttime in Alaska. I looked last week and there were plenty to be seen... and if it's clear you can at least see the stars.
It refreshes every five minutes, giving you a long stretch of (punctuatedly equilibriated) aurorical enjoyment. It's worth keeping an eye on, especially now that the nights up there are getting longer.
Sigh. No hat tip for this one; I read it on a blog somewhere and then lost the link, so I have no recollection of where I saw this. Sorry, anonymous blog, but thanks!
